摘要

污水处理设施产生的污泥含有高营养物质，具有高热值的特点。因此，富含有机物和营养物质的污泥是其作为肥料和替代能源原料的潜在候选物。如今，能源独立有助于国家的经济稳定，因此寻找替代能源是一个紧迫的问题。本文介绍了一个在波兰使用污水污泥作为能源原料的案例研究。介绍了污水污泥的理化特性。综述了不同污水处理厂产生的污泥的燃料特性。波兰产生的污水污泥的热值不足以作为能源原料有效利用，因此，研究了污泥与其他废物混合的能源潜力。污水污泥形成的总体趋势及对未来的定量预测显示，2020年污泥蓄积量比2012年增长6.9%，但比2019年下降3%。从2012年到2020年，污水污泥累积量平均每年增长0.8%。这表明了生产替代燃料的废物流的异质性，以及未来几年污水污泥产量的适度增加。这就有可能为进一步发展获取替代能源的发展技术领域的研究拟订若干备选办法。此外，本研究将有助于未来的研究人员了解污水污泥的产生及其作为能源原料的使用。

Investigation in Techniques for Using Sewage Sludge as an Energy Feedstock: Poland’s Experience

The sludge generated from wastewater treatment facilities contains high nutrients and is characterized by high heating values. Thus, the sludge enriched with organic matter and nutrients is a potential candidate for its application as fertilizers and an alternate energy feedstock. Nowadays, energy independence contributes to the economic stability of the country, and therefore the search for alternate energy sources is an acute issue. This paper presents a case study on using sewage sludge as an energy feedstock in Poland. The physicochemical characteristics of the sewage sludge are presented. The fuel properties of sewage sludge generated from different waste water treatment plant (WWTP) are summarized. The calorific value of sewage sludge generated in Poland is insufficient for effective use as an energy raw material, therefore, energy potential of mixture of sludge with other waste have been studied. The general trend of sewage sludge formation and the quantitative forecast for the future showed that in 2020, compared to 2012, sludge accumulation increased by 6.9%, but compared to 2019 - decreased by 3%. From 2012 to 2020 the average, sewage sludge accumulation increased annually by 0.8%. This demonstrates the heterogeneity of waste streams for the production of alternative fuels and a modest increase in sewage sludge production in the coming years. This made it possible to prepare several options for the further development of research in the field of developing technologies for obtaining alternative energy. Also this study will help the prospective researchers understand sewage sludge generation and its use as energy feedstock.

期刊介绍： The fundamental task set by the editors of the journal is to bring together and present a diversity of research connected with ecology. Apart from the traditional ecological research areas, the scope of the journal will embrace more peripheral ecological issues connected with other disciplines of biology. Recognizing the increasing importance of the humanities in ecological research, the editors will strive to give such issues due representation in the journal. We hope to encourage the researchers contributing to the journal to adopt an unconventional approach to solving ecological problems, to go beyond classical, well-established conceptions, and to include methodological and anthropological issues. Such an approach is validated by the intensive development of the sciences bordering on both biology and the humanities that has been observed over recent years.
